The invention relates to an electrically operable drive arrangement for venetian blinds with at least one draw tape which tape is wound up or down by a motor located in the header. Switches in the header are operated by a feeler which moves respectively perpendicular to or parallel to the tape as the tape moves from its normal tangential position on the take-up roller upon bottoming of the blind, or when the blind reaches fully raised position.
